Hi I've found that openssh-3.2.2p1 can't be compiled on my Linux 2.0.36, because it doesn't define CMSG_DATA and CMSG_FIRSTHDR in <linux/socket.h>. The patch below solved this problem.

Hello. I am trying to setup Dovecot on an Alpha running FreeBSD 4.10. I am simply trying the imap/pop3 protocols at this time. But with both protocols the log message I get is: pop3-login: fd_send(5) failed: Bad file descriptor dovecot: child 275 (login) returned error 89 or imap-login: fd_send(5) failed: Bad file descriptor dovecot: child 275 (login) returned error 89 I have tried

Everything appears to work OK apart from PrivSep (because mmap seems terminally broken). With a newer kernel with a working mmap, PrivSep might even work. Anyone complaining about old...

Hi All-- First, thanks to Timo for solving my last issue. I got dovecot up and running on one of my machines, and it does exactly what I want. Now I'm trying to install dovecot on an older box (glibc 2.0.7 Linux kernel 2.0.36), and encountering some problems: -- firstly autoconf/automake does not seem to correctly deal with the madvise function on this system. It detects that we don't

nuqneH, I've tried using TIS authsrv authentication via bsd auth and found it quite limited. The most important restriction it does not log ip and fqdn of the remote peer, nor the application name, to the authentication server. It does not matter much for TIS authsrv, but since other applications do provide such information, our authsrv version uses it for extra authentication restrictions.
